I was prescribed prednisone for my skin and 8hrs later I started to feel itchy and tingly all over. The med just made my symptoms worst! Why?!

Prednisone. Prednisone is a steroid that should not cause itching or tingling. Whatever you were prescribed it for ? You should reconsult the prescribing doctor - suspect its the underlying illness not the prednsione, but get rexamanined.
